Definitions

  • the present invention relates generally to the collection of waste, and specifically relates to methods and systems for vacuum operated waste collection of a mobile type.
  • waste deposited at different waste collection points inside or outside buildings is gathered in respective waste storage tanks or containers that are emptied by means of vacuum-equipped vehicles.
  • Said vehicles, the so called vacuum-trucks are connectable to docking stations that in turn communicate with one or several such waste storage tanks through waste pipe systems.
  • the invention overcomes the above problems in an efficient and satisfactory manner. It is a general object of the invention to provide an improved, efficient and convenient power supply for a mobile type waste collection system.
  • the invention provides methods and arrangements for integrating the power supply for auxiliary equipment of a waste collection system, in the actual system.
  • the invention provides methods and arrangements for producing electrical power for the system auxiliary equipment onboard a vacuum vehicle of the system and for supplying said produced electrical power from the vehicle to the auxiliary equipment of a storage tank in the system through an interface associated with a waste docking station.
  • One advantage of the suggested methods and arrangements is that no external power connections will be required, with an associated reduction of the costs for and problems related to auxiliary power installations.
  • a vacuum source of the vehicle is connectable to a pipe connecting interface of a docking station through a vehicle-carried pipe
  • methods and arrange- ments are provided for establishing a convenient or even an automatic connection of the auxiliary electrical power from the vehicle to the auxiliary equipment by integrating an electrical connecting interface in the docking station or in the actual pipe connecting interface.

  • the speed of the fan 40 will be controlled based on the detected air speed during the emptying sequence, and in a preferred configuration such speed control is performed by means of a variable displacement pump that is mounted on a power take-off of the vehicle 10 engine. As soon as the detected values return to normal the atmospheric air valve 47 is closed again, the speed of the fan is adjusted back to normal and the tank emptying sequence is finished in the normal mode in step S5.
